Coccygeal plexus
Coccygeal Plexus
The Coccygeal Plexus (pronunciation: kok-si-je-al plek-sus) is a network of nerve fibers located in the lower part of the spinal cord, specifically in the coccygeal region.
Etymology
The term "Coccygeal" is derived from the Greek word "kokkyx", which means "cuckoo" due to the resemblance of the bone to the beak of a cuckoo bird. "Plexus" is a Latin word that means "braid" or "network", referring to the interweaving of nerves.
Anatomy
The Coccygeal Plexus is formed by the ventral rami of the coccygeal nerve and the fifth sacral nerve. It provides innervation to the skin over the coccyx (tailbone) and the area around the anus.
